What with baking her signature cookies, prepping for her new House of Style gig, and ya know, absolutely killing it on the runway, Karlie Kloss undoubtedly has crammed enough activities into Fashion Week to make ANYONE exhausted. But while we're personally counting down the minutes til our much-needed post-NYFW nap, for Karlie it's a different story. Last night the supermodel added another activity into her packed agenda, lending her name to a seriously good cause. She attended a dinner for The Novak Djokovic Foundation, an organization established by tennis star Novak Djokovic that helps underprivileged children in his home country of Serbia. Karlie proved her special guest status for the eve in an intricately embellished v-neck gown from Carolina Herrera, simple black pumps, and black envelope clutch. With swept up hair and natural makeup (save for a swipe of liner), this is effortless perfection if we ever saw it. Who says fashion has to be dramatic?! She wasn't the only one working a sleek, relatively minimal look last night. Theophilus London proved you could look white-hot even AFTER Labor Day in crisp, clean separates.

Let's be real: we always can count on Theophilus London to leave an indelible style mark wherever he goes, whether it's LVRS x Del Toro slippers, leather camo pants, or his trademark Lennon-inspired round frames. But last night he took a lighter approach, rocking white pants, top, and jacket during his performance. The fashion rules might say white after Labor Day is a big no, but we're ALL for breaking them- and if you ask us, Theophilus looks great. We love how his black hat, shades, and animal print sleeve detail give the outfit a major pop of color without being OTT. What do you think of Karlie and Theophilus's "less is more" Fashion Week looks? Tell us in the comments!
